TT electronics is a focused, global electronics
company supplying the world s leading medical
electronic equipment manufacturers as well
as independent design firms engaged in high-
reliability medical and healthcare systems
design.
TT electronics products have long been
specified for a number of applications in
medical devices and equipment. In addition
to electronic components, TT electronics also
provides complete solutions through advanced
manufacturing services for medical systems,
including design support, application
engineering assistance, and advanced testing
for medical electronics. TT electronics
passive components, optoelectronics, and
semiconductors are used extensively in
diagnostic, imaging, laboratory equipment,
patient monitoring systems, instrumentation,
and pharmaceutical delivery and dispensing
systems.
Individual TT electronic divisions specialize
in standard and application specific products
including microelectronic assemblies,
magnetics, optoelectronics, sensors, resistors,
resistor networks, and precision potentiometers.
As a combined company, TT electronics can
serve as a single-vendor source for this wide
range of medical-qualified products as well as
specialized technologies needed to develop
innovative custom solutions.
The TT electronics component divisions
have manufacturing sites strategically
positioned worldwide, three of which are
ISO 13485:2003-certified, allowing them to
manufacture medical electronic systems. All
manufacturing facilities are ISO 9001 certified,
and several of the sites are TS 16949:2002
certified as well.

Diagnostic, Imaging, and Laboratory
Advances in medical diagnostics, laboratory, and imaging technology have redefined how physicians diagnose
and treat a range of pathology from common illnesses to the most life threatening diseases. These advances
have significantly reduced the need for invasive exploratory surgery, and improved detection of diseases, which
allows more accurate and timely diagnosis and treatment. Advancements in this technology have allowed the
move from the hospital inpatient setting to outpatient facilities and physician offices resulting in lower cost and
more timely access for the patient. TT electronics has extensive experience in partnering with our customers
to develop and produce a wide range range of high reliability electronic components and device systems to
support innovative diagnostic, imaging, and laboratory equipment.
